![]() Here’s the same example resolved using the underscore name: a, b, _, c = Īlternatively, you can also use the asterisk operator on the left-hand side as will be explained at the end of this article-so keep reading! ? ValueError: not enough values to unpack (expected x, got y) Per convention, if you don’t need to store a certain list element in a variable, you can use the “throw-away” underscore variable name _. To resolve the ValueError: too many values to unpack (expected k), make sure that the number of elements on the right and left-hand sides of the unpacking operation is the same. ![]() ValueError: too many values to unpack (expected 3) This can be seen in the following code snippet: a, b, c = įile "C:\Users\xcent\Desktop\code.py", line 1, in ![]() If the list has too many values to unpack - i.e., the number of elements in the list is larger than the variables to assign them to - Python will raise a ValueError: too many values to unpack (expected k) whereas k is the number of variables on the left-hand side of the assignment operation. # 3 ValueError: too many values to unpack (expected k) Each variable captures one list element after the unpacking operation. In the following example, you unpack the three elements in the list into variables a, b, and c. List unpacking is the process of assigning k elements of a list to k different variables in a single line of code. For it to work, you need to have enough variables to capture the number of elements in the iterable. ? Iterable unpacking or sequence unpacking is the process of assigning the elements of an iterable (e.g., tuple, list, string) to multiple variables. Python allows you to assign iterables such as lists and tuples and assign them to multiple variables. ValueError: not enough values to unpack (expected x, got y).ValueError: too many values to unpack (expected k).In this article, you’ll learn about the following topics:
